2si 460 explained

The 2si 460 is a family of in-line twin-cylinder, two-stroke, single ignition, aircraft engines that were designed for ultralight aircraft.[1]

The basic engine was originally designed and produced by ILO-Motorenwerke of Germany and was later acquired by the AMW Cuyuna Engine Company of Beaufort, South Carolina and marketed under the Cuyuna brand name. Later the engine was marketed by Cuyuna under the Two Stroke International (2si) brand. Cuyuna no longer markets engines for aircraft use, although the 460 is still in production as a Diesel/multifuel or gasoline industrial, marine and sport vehicle engine.[2] [3] [4] [5] [6] [7]

The 460 is a conventional twin-cylinder engine that weighs 590NaN0 in its F35 aircraft version. The engine features single capacitor discharge ignition, piston porting, tuned exhaust system, one or two slide venturi-type carburetors, fuel pump, a cast iron cylinder liner, ball, needle and roller bearings throughout. The aircraft version was offered with cog belt drive or a gearbox reduction system. Starting is electric starter or recoil starter.
